CodePush is a cloud service that enables Cordova and React Native developers to deploy mobile app updates directly to their users’ devices. It works by acting as a central repository that developers can publish certain updates to (e.g. JS, HTML, CSS and image changes), and that apps can query for updates from (using our provided client SDKs).
With React and React Native, your web app can share most of its logic with your iOS and Android apps, but the view layer needs to be implemented separately for each platform. We have taken this a step further and developed a thin cross-platform layer we call ReactXP. If you write your app to this abstraction, you can share your view definitions, styles and animations across multiple target platforms. Of course, you can still provide platform-specific UI variants, but this can be done selectively where desired.
Instantly test your code on a device, or in the browser. You can either preview the component on the emulator inside the browser, or open it directly on your device with the Expo app. The UI updates as you type — every keystroke, without having to hit save.
